Application filed June 1,

This invention relates -vto marker blocks and is particularly useful to carpenters. The device constructed in accordance with my invention is particularly employedv in marking off spaces onthe edges of doors which are to be mortised for the reception of hinges.

An object of my invention is the pr-ovision of a simple, economical and eiiicient marker block.

lVith the foregoing `object in view, together with such other objects and advantages as may subsequently appear, this invention resides in the construction and` arrangement of parts hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a marker block.

Figure 2 is a vertical section taken on line 2 2 of Figure 1, and

Figure 3 is an end view of the marker block in inverted position from that shown in Figure 1, the block being applied to the side of a door for the purpose of mai-king off an area. to be mortised.

Referring to the drawings for Vmore detailed description thereof, the numeral 5 indicates a rectangular block which may be of any suitable material, such for example, as steel. The upper half of the block is 'slightly narrower than the -lower half and also slightly shorter, in order to provide edges.

6 and 7. Marking means are provided on the marker block and such means are herein shown as comprising plates 8, 9, 10, 11, 12, and 13. The plate 13 rests on theend ledge 7, while the plates 9 to 12 inclusive rest on the ledge 6. All of the plates extend above the upper surface14 of theblock and all have sharp acute angled upper edges. Screws are employed, as shown, to secure the plates to the block.

The vertical plate 8 is provided with a flat iiange 8a, which. lies on the face 14 of the block. Recesses 16 are provided on the upper face of the block so that the plateV 8 may be adjusted relative to its distance from the end plate 13, whereby any desired length may be marked off on'an object which is to be cut away.r

The plates 9 to 12 inclusive are preferably of multiple or sub-multiple lengths of an inch. For example, the plates 9 to 12 inclusive are respectively one inch, one-half inch, one inch, and two inches in length,

1926. Serial N0. 112,945.

The plates 9 to 12inclusive'are removable so that when the plate 8 is moved closer to the plate 13 than is shown in Figure 1,'one or more of the plates r9 to 12 inclusive may .be removed so that no plate projects beyond the plate 8.

It will also be noted that the plates 10 and 11 may be interchanged iii position, whereby the side plates collectively may be of different lengths and the plate 9 is removed and one of the plates 10 and 11 also removed, with the remaining plate fixed adjoining the plate 12. In fact the plates 9 to 12 may, if desired, be made to interchange in a variety of ways.

Adjustably secured to the upper face 14 of the block 5 are .guide members 17 comprising vertical members 18 parallel with the plates 9 to 12 inclusive. The guide 17 comprises flat portions 18a` lying on the upper face 14 of the block and provided with elongated slots 19,'through which pass screws 20, each of which engages one of the holes 16. The guides 17are adjustableso that the plates 9 to V12 inclusive may mark ofi" an area of any desired width when the guides engage the side of a block, as shown in Figure 3.

It will be noted that the guide 17 may be rotated through one hundred and eighty (180) degrees, and a further adjustability may thereby be secured.

The lower face 20 of the block 5, as shown in Figure 2, is provided with a flange 21, adapted to hold therebetween a body of comparatively soft material which may be for example, paper ber, and which is provided to avoid breaking the block when it is hammered to mark an object by means of the marking plates.

Figure 3 shows a marking block described as applied to the side 24 of a door 25. The block shown in this 'ligure is inverted from the positions shown in Figure 1, the guides 17 contacting with the left vertical face of the door.

With the block in position, as shown iii Figure V3, it is hammered on the padding 22 and the marking blades cut into the door to the out may be regulated by the thickness of the horizontal portions 18 lof the guides 17.

While I have describedone embodiment of my invention, modifications thereof may be readily devised without departing from the spirit of my invention, and it is tov be under,

define the area to be mortised. The depth of lli) stood that such modifications come witliii the scope of the appended claims.

I claim 1. A marker device comprising a block, marking means extending beyond a face of the block, said means comprising a. plurality.

of marking plates of different lengths, and

having screwsreceiving holes therein, screws detachably securing said plates to said block, the apertures in said plates being so disposed that the plates may be interchanged while allowing the apertures therein to register with the original screw holes in the block.

2. A. marker device comprising a block, marking means extending beyond aface of the block, said means comprising a plurality of marking plates of dierent lengths, and having screw-receiving holes therein, screws detachably securing'said plates to said block, the apertures in said plates being so disposed that the pla-tes may be interchanged while allowing the apertures therein to register with the original screw holes in the block, and L-shaped guides slidably and rotatably-secured to the block by screws 'passing thru elongated slots inthe guides, said guides having Vertical portions spaced from said marking blades.
